The femaleattachment member 20 can also include an external annular flange 42 thatcontacts the proximal end 16 b of the treatment member 16.

In use, to connect the treatment assembly 12 on the shaft 102, thefemale attachment member 20 is threaded onto the male attachment member14 until the distal end 104 of the metal shaft 102 comes into contactwith or is closely adjacent to magnet 18. The reciprocal treatmentdevice 100 can then be used to massage the user's body part. To changetreatment assemblies, the first treatment assembly is unthreaded fromthe male attachment member and a second treatment assembly is threadedthereon.

FIGS. 5-7 show another embodiment of a treatment assembly 50 that can besecured to the shaft 102 of a reciprocal treatment device using theattachment system 10. As shown in the drawings, in a preferredembodiment, the treatment assembly 50 includes similar components to thetreatment assembly described above, but includes a differently shapedtreatment member 52 and female attachment member 54. Preferably, thetreatment member 52 is made of an elastomeric or compliant material(e.g., rubber, silicone), is generally hollow, and includes acompressible portion 56 between the distal and proximal ends 52 a and 52b. With this arrangement, during use, the treatment member compresses orcollapses, thereby providing a softer impact than the treatment member16 described above.

As shown in FIGS. 5-7, the treatment member 52 includes a first annularoutwardly protruding portion 58, a second annular outwardly protrudingportion 60 and the compressible portion 56 disposed therebetween. Inpreferred embodiment, the second annular outwardly protruding portion 60has a larger diameter than the first annular outwardly protrudingportion 58. The compressible portion 56 also includes an annularinwardly protruding portion 62. The compressible portion 56 firstannular outwardly protruding portion 58, second annular outwardlyprotruding portion 60 and annular inwardly protruding portion 62 allwork together to provide compression and spring back of the treatmentmember 52 during use. In other words it has a spring like action thatabsorbs some of the impact to the body or subject of the treatment.

The female attachment member 54 preferably includes an annular collar 64that interacts with the inner surface of the treatment member 52 tosecure the two components together. The annular collar 64 includes aridge 66 thereon that is received in a trough 68 created by the firstannular outwardly protruding portion 58. It will be appreciated that thehollow compressible treatment member 52 can be used with any of theattachment systems taught herein and shown in any of the drawings. Inother words, the hollow compressible treatment member 52 is not limitedto the magnet attachment system, but can also be used with theattachment systems shown in FIGS. 8-13 below.

FIGS. 8-10 show another embodiment of an attachment system 70 that canbe used with a reciprocal treatment device. As shown in FIG. 8, in apreferred embodiment, the attachment system 70 generally includes atreatment assembly 71, a male attachment member 72, and a disc 74.

In a preferred embodiment, the female attachment member 76 includes atleast one and preferably a plurality (two are shown in the drawings) ofspring biased balls 78 or plungers that cooperate with openings ordetents 77 defined in the disc 74 or in the male attachment member 72,as described below. Preferably, the female attachment member 76 includesan annular flange 79 extending outwardly from the main body portion thatincludes recesses 80 in which the balls 78 are seated. The recesses 80can include a spring 81 or any other type of biasing mechanism thatbiases the balls 78 outwardly or upwardly.

In a preferred embodiment, the female attachment member 76 includesinternal threads 30, and the male attachment member 72 includes externalthreads 32 for mating with the female attachment member 76. In use, toconnect the treatment assembly 71 on the shaft 102, the femaleattachment member 76 is threaded onto the male attachment member 72until the balls 78 are received and biased into the detents 77, as shownin FIG. 9. The reciprocal treatment device 100 can then be used tomassage the user's body part. To change treatment assemblies, the firsttreatment assembly is unthreaded from the male attachment member and asecond treatment assembly is threaded thereon. It will be appreciated bythose of ordinary skill in the art that the springs 81 are chosen withthe appropriate spring force so that the balls 78 are biased with enoughoutward force to keep them in the detents 77 during use of thereciprocal treatment device (to prevent rotation and accidentalseparation of the treatment assembly 71 from the shaft), but, when thetreatment assembly 71 is unthreaded, due to the curved surface of theballs 78, the edges of the detents 77 push the balls 78 inwardly so thatthey come out of the detents 77 and the treatment assembly 71 can beremoved from the shaft.

In a preferred embodiment, the male attachment member 72 and shaft 102include transverse openings defined therethrough that receive a shaft 82that secures the male attachment member 72 on the shaft 102. In anotherembodiment, the male attachment member 72 can be secured to the shaft102 as described above in the first embodiment or by any other method(glue, welding, adhesive, threading, etc.). A magnet can also beincluded in this embodiment, if desired.

The maleattachment member also includes balls 90 that are spring biasedoutwardly from the opposing flat surfaces 89. Any biasing mechanism iswithin the scope of the present invention. In a preferred embodiment,one or more springs 94 bias the balls 90 outwardly.

In a preferred embodiment, the treatment assembly 87 generally includesa treatment member 16, and a female attachment member 91. The treatmentmember 16 includes a distal end 16 a and a proximal end 16 b with anattachment recess 22 defined therein. The female attachment member 91includes a distal end 91 a and a proximal end 91 b and is secured in theattachment recess 22. The female attachment member 91 preferablyincludes a shaft recess 24 defined adjacent the proximal end thereof.The female shaft recess includes first and second flat surfaces 92 thathave detents 93 defined therein. The balls 90 on the male attachmentmember 88 are configured to be received in and cooperate with thedetents in the female attachment member 91. Furthermore, the first andsecond opposing flat surfaces 89 of the male attachment member 88 areconfigured to cooperate with the first and second flat surfaces 92 ofthe female attachment member 91 to prevent the two from rotating withrespect to one another. In another embodiment, the interior surface ofthe female attachment and the exterior surface of the male attachmentmember can be square or rectangular or include other shapes that allowthe female attachment member and male attachment member to mate and beprevented from rotating with respect to one another. It will beappreciated by those of ordinary skill in the art that a single flatsurface on each will prevent rotation.

To change treatment assemblies, the first treatment assembly is pulledaxially off of the male attachment member and a second treatmentassembly is placed on the male attachment member. It will be appreciatedby those of ordinary skill in the art that the spring(s) 94 are chosenwith the appropriate spring force so that the balls 90 are biased withenough outward force to keep them in the detents 93 during use of thereciprocal treatment device, but, when the treatment assembly 87 ispulled outwardly (away from the shaft in an axial direction), due to thecurved surface of the balls 90, the edges of the detents 93 push theballs 90 inwardly so that they come out of the detents 93 and thetreatment assembly 87 can be removed from the shaft.
